Gareth holds a B.Sc. in Natural Sciences/Chemical Engineering from Cambridge University, and a Ph.D. in Chemical Engineering from MIT. He is a recognized authority on rheology, fluid dynamics, mathematical modeling and experimental design for rheological characterization. Gareth is a tenured professor at the Massachusetts Institute of Technology in the Department of Mechanical Engineering, as well as a co-founder of CPG. He has experience with flow modeling, rheology of changing materials, and material design. Gareth is the editor of the Journal of Non-Newtonian Fluid Mechanics.

Steve has over 10 years of experience in analytical characterization of materials. He has a B.Sc. in Chemical Engineering from the University of Wisconsin-Madison, and a Ph.D. in Chemical Engineering from MIT. Before forming Cambridge Polymer Group, Steve conducted post-doctoral research at Harvard University, where he examined the extensional rheology of polymer solutions. His work at Cambridge Polymer Group has focused heavily on polymers used in biomedical applications, including polyethylene and various hydrogel systems. Steve has developed a novel rheological technique to examine the conditions that could lead to failure of the cement-stem interface in THR. He has also designed test methodologies and processing steps for the crosslinked polyethylenes used in hip and knee replacements, and holds several patents in this area. He has experience in instrument design and fabrication. He chairs several ASTM task forces.

Gavin manages the R&D efforts at CPG. He has been working with colloids, surfaces and polymers in solution for over 15 years. He has a B.Sc. in Physics from Edinburgh University, specializing in acoustics and fluids, a Masters in Electronics from Southampton University, specializing in digital radio communication strategies, and a Ph.D. in Chemical Engineering from Imperial College (London), where he worked adsorbed polymer layers and colloidal stability. For this work, he built and used an AFM to probe the interparticle forces due to adsorbed polymer layers. He is an expert in instrument design, having designed an atomic force microscope for his thesis and a number of custom instruments since joining CPG. He also designed a micro-shear rheometer as part of his post-doctoral research at MIT, where he investigated the rheology of confined polymer solutions and melts. He has a number of issued patents on topics as diverse as an extensional rheometer (now marketed as the CaBER), a method for making biomimetic collagen layers, and on methods for making, and uses for, hydrogels. At Cambridge Polymer Group, he is managing the main research efforts. Gavin has expertise in polymer gel formulation and characterization, and focuses a large part of his research on associating polymer systems. His primary interest is polymers in solution and in colloidal systems.
